The Biopsychology of Sleeping and Dreaming

[@OrangeMilks]

I have narcolepsy (and cataplexy) and had to sleep at the hospital with all those electrodes on my head (and some on my legs cus I also have restless leg syndrome lol). I got to see the Wave chart the next morning. I remember they said I my brain basically fell asleep(REM) before I closed my eyes, which was kinda freaky. But I did hallucinate a lot back then, so it makes sense. I “slept” 8 hours, but overall barely stayed 45 mins in stage three. I spent most time in REM sleep and woke up every other hour. AND THEN you have to get up and live your life but you’re still so tired and exhausted that you fall asleep as soon as you sit down or do something monotonous during the day. Because you NEVER get a good nights sleep. It’s been like that for 9 years now, I barely remember how it felt to wake up well rested, feeling alert or spirited. Drugs help a lot..! But they also make you feel... drugged. Sorry for rambling on! SLEEP IS JUST VERY INTERESTING! Very good video!

I tried taking Vitamine b Complex, so also! b12 important, and it helped me alot. Praximepol made me tired for that.

oh the intro is amazing!

Good review. But we need to add the spiritual dimension to sleep. Couple of my dreams had conviced me of this dimension. One dream in particular leaves no room for another justification. During my student days in USA, I saw one of my father's aunts in a dream. She was wearing a white robe, indicative of death. It was in early 1980s when communication was crude compared to today. While dreaming I heard the telephone ringing. My telepathic sense alerted me that the call was related to my dream. On responding to the call I asked whether she was dead. Surprisingly the caller wad the son of the person I was dreaming of. He infact confirmed that his mother has passed away and he was calling me to pass the message. The call came from the Maldives, which has a nine hour time difference from my location in New. This is convincing for the spiritual dimension of dreams.

You just confirmed why I am here

Very hard to prove 'spiritual' sides of things, as most if not all of those can't be quantifiable and can't be properly proven. Ive had a similar dream wherein the exact same scenario in my head happened the day I also woke up. But I doubt as of today's technology, we could give certain proof about outside realms or dimensions

[@crazyev7020]

How does exactly we respond while sleeping? Some people have this habit..but I'm a heavy sleeper

[@HelgatheHorriblez]

I have KLS and I can attest to the recuperation theory. When I get sick, have a Behcet’s Disease flare or experience a physical trauma (like a burn) I end up going into a KLS event and spend days to weeks-sometimes months asleep. If I am feeling generally unwell for an extended amount of time- I can feel my body demanding long term sleep that can result in me sleeping in strange locations (like closets in high school) or completely shutting down until my body is well again. When I wake up from such events- I physically feel better, but remember very very little if anything of my “wakeful periods” and usually if someone feeds me while I’m sleeping- I’ll eat anything in excess and can result in weight gains. We have rules now- that if I’m “too tired” to go to the table to eat- then I’m not to be fed.

Re: the seemingly cyclical nature of sleep I wonder if it has to do with the metabolic waste that accumulates in the brain. Doesn’t the brain flush that out during sleep? So maybe that’s why we need to sleep in this 24hr interval. Maybe the build up of that waste causes the brain synapses to slow slightly, so the body experiences grogginess and slowed reactions? Otherwise couldn’t we consume enough energy to stay away for longer periods? Idk anything tbh, so don’t be too mad if I’m sounding like a complete fool 😆

[@foreverNwonder]

It deeply bothers me that I can rarely remember my dreams. Only if I’m awakened due to noise or having to pee, do I remember my dream. But the more I try to access the memory, the faster it fades. It’s like trying to grab a thin scarf as it falls through the air… just as my brain recalls, it slips away. I don’t understand how ppl are able to write their dreams down. I wake up & write random words occasionally.. but nothing that makes sense.

I got an ad for a catholic prayer app lol 😂

[@Zetsuke4]

Very nice

[@thomaslong8401]

I wish I were more like a horse with 2 hours of sleep. I’d get a lot more done. But it would be hard to use my phone though.

[@MiltosPol-qn3zh]

Proffesor, what video should I start watching first in o chem??? And any advices or further videos to watch???

[@ProfessorDaveExplains]

just go to the organic chemistry playlist and start from the top!

[@brittniep9219]

Agreed! I just took ochem. Really understand resonance, stereochemistry, Rotating molecules in space, nomenclature, different projections/conformations (Newman, Fischer, chair) and then start practicing synthesis and reaction mechanisms ASAP! :)

[@sanjanadilse1742]

Good

[@seanchavez2970]

Wouldn't go to far I to yea futurama is cool, but it has defaults

[@SpaghettiToaster]

4:20 how does this imply that most dreams are meaningless though? It doesn't really matter where the information supplied comes from, it's still filtered through the cortex and hence patterns that show up in dreams are clearly influenced by the patterns in the brain, which obviously correlate with a whole lot of things, such as memories and personality traits.

[@hanoufnouf5278]

What are the references to this video? any articles or studies related?

[@hajiqasim448]

you are great professor. you have got a lot of subscriber

[@EMERSON5]

Nice job! Very informative.

[@realcygnus]

Good one, as usual.

[@adleneboulebtateche156]

A great video. Thanks a lot Professor.

[@out_of_control1]

The hypothalamus part of the brain is where Alzheimer's is affected. Do you believe that sleep deprivation could be a common denominator for the illness? Pardon I asked this Q before I got to 7:58

[@sanjanadilse1742]

But not a new thing

[@ProfessorDaveExplains]

Yes, sleeping is not new.

[@johnroydeguzman9691]

Damn I miss your hair.

[@horizonbrave1533]

Love it! So is there any merit to the idea/theory that the actual 'dream' that we have is experienced in the last few seconds of sleep? I heard that during the N3 cycle, our brain is inundated by images experienced through out the day each time we cycle back to N3. Then at the end of our sleep, and as we wake, in order for our brian to make sense of all the images it creates a very loose story or narrative to connect all the images. Hence why dreams are always so bizarre at times? So there's no real meaning, but it's just a way for our brain to connect images we've seen

[@CaptainBohnenbrot]

How do we know how much hours of sleep a giant sloth needed?

[@emmah8786]

so helpful for my final exam thank you!

[@berakahemmanuel6672]

Good info but too many ads 😢

[@herald246]

This is gold! Thank you!

[@drhfhs]

Certainty slows us down so much technologically and socially . Arrogance, close minded Ness is a human nature which if man had mentally overcome in an alternate reality , we would own the stars the galaxies .

[@radinelaj-c7s]

🤔, the brain is like microphone, or antenna, absorb the waves( special waces,signals).strange

[@babarazamsucks]

First!
